About this app

DDD Connect is the professional mobile solution for downloading and managing tachograph data. Designed for transport operators, compliance managers, and fleet owners, it connects via Bluetooth to DDDKey devices and quickly and securely downloads tachograph memory and driver cards.

BLUETOOTH DOWNLOAD, NO HASSLE

Connect your DDDKey and, in just a few taps, download:
• The driver card (slot 1 or slot 2)
• The tachograph memory (customisable period and data sections)
• Both in a single operation

When the download is complete, the DDD file is immediately available in the archive and automatically linked to the driver or vehicle.

ALWAYS UP-TO-DATE ARCHIVE AND REGISTRY

All files are stored locally on your device — no cloud, no data shared externally. From the archive you can view file properties, verify digital signatures, share or export data as a ZIP.

The driver and vehicle registry updates with every download: you always have the latest download, driver card expiry, and next tachograph calibration date at hand.

DEADLINE TRACKER: NEVER MISS A DATE

The built-in deadline tracker monitors all regulatory requirements:
• Mandatory download dates for driver card and tachograph memory
• Driver card expiry and renewal
• Periodic tachograph calibration

Push notifications arrive in advance so you can plan ahead. The home screen widget gives you a quick overview of upcoming critical deadlines.
